MA CHlNE FOR BENDING BAILS.

SPECIFICATION forming part of Letters Patent No. 252,551, dated January17, 1882.

Application filed October 17, 1881. (No model.)

- To all whom it may concern:

-the city and county of Providence, State of Rhodelsland, have inventeda new and useful Improvement in Machines for Bending Bails; and I herebydeclare that the following is a fnll,clear, and exact description of thesame, reference being had to the accompanying drawings, forming part ofthis specification.

This invention has rcferenceto an improve ment in machines for bendingthe bails for buckets, kettles,and other articles; and it consists inthe peculiar and novel arrangement of pivotally-connectedbending-levers, a reciprocating former, and pivoted arms constructed toform the eyes of the hail, the wholearranged to form the complete bailat one operation, as will be more fully set forth hereinafter.

Figure 1 is a frontelevation of myimproved machine. Fig. 2 is an endview of the same. Fig. 3 is a sectional view of the spring-pressed boltsbywhich the levers bending the eyes are operated. Fig. 4 is a skeletonview, showing the operating devices in the position occupied when theformer descends to bend the bail. Fig. 5 is a skeleton view, showing thedevices in the position occupied by them when the bail is completed.Fig. 6 is a vertical section on line as w of Fig. 1. Fig. 7 is askeleton view of the wire-bendingdevices at a point of their operationintermediate of the beginning and tinishing, as shown in Figs. 4 and 5.

111 the drawings, Arepresents the former secured to a reciprocatingslide, A, which lies behind the supporting frame orstandard' S, and hasa screw-stud, a, projecting forward through a vertical slot, a, in saidstandard, this stud passing through the former, which is secured thereonby a suitable nut.

B B are the lower bending-levers, provided with the rollers b b andpivoted at 0 0. These le-- vers are connected by springs t t with thelaterally-projecting arms 8 s of the standard, the upper ends of thelevers lying behind said standard. The rollers b b are in front of thestandard and mounted on pins 1) b, which project forward from the endsof the lovers and through the curved slots 12 o in the standards.

0 G are two rests pivoted at the lower end, and kept in position by acoiled spring, 0, as is clearly shown in Fig.2. The upper inner cornersof these rests stand under the levers B B and prevent them fromdescending belowa certain point, except when said rests are removed.

D is a curved pro ection extendlng from the rests C O, and E is awedge-shaped cam attached to the slide A,and which,on descending, passesbehind the projection D and withdraws the rests U G from under thelevers B B. allowing the free ends to descend with the follower and bendthe bail inward.

, F F are two adjustable guides which project forward from the arms 8 sof the staudard,and

by which the ends of the blank are held and prevented from turning upuntil the ends are drawn from under the same.

H H are the upper curved bendinglevers, pivoted on a common pivot, hto'the lower portion of the follower I, which is supported by an armprojecting through the slot at from the slide A. The long arms of thelevers H H are curved downward, and the short arms curve slightly upwardfrom the pivot, and are provided at their ends wit h rearwardly-projecting studs h h, which normally rest in notches h formed in the loweredge of the follower I.

g g are two spring-pressed bolts, with which the ends it h of thepivoted bending-levers H H come in contact as the follower I descends,.80

so as to bend the ends of the bail into eyes by the co-operation withthe studs h h of the bending-levers H H, as is shown in Fig. 5. Theouter ends of the bolts g are connected by a bar,g and slide in sockets9 formed at the tops of vertically-adj ustable arms G, which are securedto the laterally-adjustable standards G by slot-and-bolt connection. Thebar g is provided with a handle, 9 The follower I is constructed toslide in ways, and is counter- 0 balanced by the weight K. The followerand its sliding carriage may be operated by means of the bars Lconnecting with a foot-treadle or with any other means for operating thesame.

N N are adjustable stops for the bail-blanks, 5

O O are studs projecting downward from arms 1) p, which projectlaterally from opposite sides of the slide A. At the lower ends of thesestuds are pivoted rollers O O, which at a proper point in the operationof the machine strike the upper edges of the levers B B, and force saidlevers dow-nward.

The operation of the machine is as follows: The stops NN being properlyadjusted, a blank, as shown at M, (which is simply a wire rod of properlength to form a bail,) is laid upon the rollers b b with the endsextending under the stops F F. The slide A is then forced downward bymeans of a treadle connected with the bars L L, and the former A strikesthe blank and bends it down between the rollers I) b. When the blank isthus bent to the degree for which the wedge-cam E is adjusted, said camstrikes the curved piece D, forcing the rests G from under the levers BB, and immediately following the removal of these rests the rollers O Ostrike the upper-edges of the levers B B, forcing the inner ends ofthese levers down and the rollers b 1) toward each other. The former A,in the meantime, having passed below the rollers b b and drawn the endsof the blank from under the stops F I these ends project upwardlybetween the rollers b 1). Previous to this point in the operation of theparts named the ends it h of thelong arms of the upper bendinglevers,HH, have struck the bolts 9 g and are forced upward, as shown in Fig. 5,throwin g the short arms of said levers downward, so that as the ends ofthe blank escape from the stops F F and. spring upward they are struckon their upper sides by the studs h h of the short arms of levers H H,and now as the levers B B are further forced downward by the rollers OO, and the rollers b b bend the blank over the former, as shown in Fig.5, the studs h h, also descending with the slide and follower I, bendthe ends of the blank down and around the rollers b I), thus forming theeyes of the bail, as shown also in Fig. 5. The bail is now completed,and in order to remove it from the machine the bar g is drawn outwardbyits handle 9 thus drawing the spring bolts g into their sockets andfrom under the ends of the elevated long arms of levers H, so that theselong arms fall by gravity to their normal positions and the short armsare raised from in front of the rollers b I). The operator may thenseize the lower portion of the bail and draw it off the former, and atthe same time the eyes slip off the rollers l) b. A suitable notch, q,is formed in the lower edge of the former to enable the operator tograsp the bail, which having been removed,the parts are allowed toassume their normal positions ready to operate upon another blank, theweight K drawing up the slide, and the springs t t raising the levers BB.

Having thus described myinventionlclaim as new and desire to secure byLetters Patent 1. The combination, with the pivoted levers B B and thelevers H H,ofa reciprocating follower provided with the former A, thebolts 9 g, and bearin gs F F, constructed to operate as and for thepurpose set forth.

2. The combination, with the pivoted levers B B, provided with therollers b b and the reciprocating former A, of the rests O 0,constructed to be removed when the former has descended part of itsstroke, and thus allow the free ends of the levers to bend the bail overthe former, as described.

3. The combination, with thelevers B B and H H and the reciprocatingformer, of the spring-pressed bolts 9 g, as described.

4. The combination, with the reciprocating former A, secured to asliding head,and means for forcing the former on the blank, of thehinged lever B B, the supports 0 O, and means for detaching the same,the rests F F, boltsg g, and levers H H, the whole constructed to bend abail at one operation, as described.

In witness whereof I have hereunto set my hand.

SAMUEL VANSTONE.
